Load Monitor TTLM


TTLM is a load monitor without display meter, 1-4 channels connection possible. It is the cheapest load monitor system.
・Signal conditioning module for strain gage sensors and load cells
• Four independent channels for accommodating up to eight sensors
• For use with full bridge sensors from 120 Ohms to 1,000 Ohms
• Plug-in connectors are used for sensor inputs
• High/low sensitivity span ranges selected with front panel switch
• Automatic zero balance circuits assure accurate measurements
• Power input/output are plug-in connectors • Built-in automatic peak load memory circuits
• Peak measurements are made with an external trigger device• Built-in power supply for stable operation and noise rejection • Compact size to fit almost any location
• Steel enclosure for maximum protection and noise rejection
The new TTLM I/O Load Module has been designed with user friendliness in mind. The unit incorporates the use of Phoenix Connectors on the sensor inputs as well as the analog output for easier wire installation. The TTLM was designed to condition the output from most 350 Ohm bridge sensors such as Toledo Transducers, Inc. T400 Load Sensors or load cells. It provides an analog output in the range of +/-9 VDC for use by many standard A/D conversion products. Several useful functions such as auto-zeroing and peak hold circuits have been incorporated to make the TTLM a versatile signal conditioner.
The TTLM is a signal conditioner which can be used as an input to a PLC or a PC with the appropriate software to convert the TTLM’s analog signal into a useable digital tonnage reading.
